If there was artillery though, you'd have to take some infantry/armor support with you or else enemy halftracks with infantry should be allowed to overrun you quickly.
Thus, when the arena full artillery would require coordination with yer buds.
But it would be great in tank town, forward armor could have coordinates called in for anything they spot if you are in the commanders seat.
Also, it would be quite susceptible ot air attack, but teh payoff would be firepower.
In quiet arenas, neglected corners, etc. you could pork a base or supply setup PDQ.
